When RS12 was operating over Europe on a normal day, there were many CW and SSB stations from one end of the transponder to the other. FO20/29 on the other hand I find to be most disappointing, with only about 10 percent of its bandwidth in use, mostly SSB, with one or perhaps 2 CW stations. Even AO40 seems to have spare bandwidth at the upper end of the uplink, maybe it's different in the U.S. It begs 2 questions, why was RS12 more popular and do we really need such wide bandwidth transponders. I believe a lot of HF stations have a 2 metre transmitter for local work and can be tempted into trying satellite mode, lets exploit it. (that's how I started and got hooked).
